The body of a child found partially burned inside an apartment on Milwaukee's south side has been identified as a 4-year-old boy, authorities said Friday.

Antonio Distasio was discovered early Thursday after firefighters were called to a report of a smell of smoke coming from the residence in the 1700 block of W. Grant St., Milwaukee police said.

Hours after the grisly discovery, a 23-year-old woman was taken into custody on a potential charge of first-degree intentional homicide, according to police arrest logs.

The child's cause of death remains under investigation, and an autopsy was scheduled for Friday morning.

A police spokesman confirmed the woman is a family member of the boy and said she would be referred to prosecutors for possible charges in the coming days.

The woman has not faced any previous criminal charges in Wisconsin, according to online court records. The Milwaukee Journal Sentinel typically does not name uncharged suspects.

Police also are asking any witnesses to contact detectives and are specifically seeking one witness who spoke with firefighters at the scene on Thursday. Anyone with information is asked to call police at (414) 935-7360.
